Dell's XPS line has been part of the 13-inch ultrabook world since its introduction at CES 2012. In the six years that have passed since then, the line has seen a steady series of upgrades, largely just to keep up with the march of technology. However, the latest revision is arguably the biggest one the XPS has seen since its introduction.
That said, Dell hasn't exactly redrawn the blueprints. The machine is still designed with portability at top of mind. If you're the type of person who tries futilely to work on a flight, only to be completely stymied when the person in the seat in front of you reclines an inch, a laptop like this makes sense. At 2.7 pounds and 19mm of thickness, it isn't the thinnest nor the lightest machine on the market, but it's svelte enough to slip into any carry-on, and compact enough to fit on a tray table alongside your complimentary ginger ale with no problems at all.
Cosmetically, numerous changes have been made to the XPS 13. Some of these are subtle, like thinner bezels around the display, a brighter screen, and revamped thermal engineering. Others are more readily noticeable, like the speakers now located on the sides of the chassis, adjacent to the space bar, and the "woven glass fiber" palm rest that comes with the rose gold/white version of the machine. (A more traditional black chassis with a carbon fiber palm rest is also available.) I don't find the textured glass fiber very attractive, and can only imagine how those ridges will fill up with meat-paw grime after months of daily use. Your mileage may vary, along with your cleanliness.
Under the hood, it's a tough little machine. Benchmarks are solid but on par with the field, and its 6-hour, 20-minute battery life score (on a video playback test) is above average. My tester was configured with an eighth-generation Core i7, 16GB of RAM, and a 512GB SSD. The 13.3-inch touchscreen dazzles at 3840 x 2160 pixels, and though Dell has jettisoned all of the unit's traditional USB ports, they have at least been replaced by three USB-C connectors, one of which is used for power. A microSD card slot provides the only other physical connectivity option here aside from a headphones jack.
